How long does it take for biofilm to form on the pellicle after a coronal polish?

The time it takes for biofilm to form on the pellicle after a coronal polish is approximately 1-2 hours. This process reflects the rapidity at which microorganisms can colonize surfaces in the oral cavity. After the removal of dental plaque or during professional cleanings like coronal polishing, a pellicle—a thin film of salivary glycoproteins—forms almost immediately on the tooth surface. Following this, bacteria begin to adhere and reproduce, leading to biofilm formation.

This timeframe emphasizes the importance of maintaining good oral hygiene practices soon after professional dental procedures. If plaque control measures are not taken within this window, plaque can re-establish quickly, leading to potential oral health issues. Understanding this time frame helps dental professionals inform patients about the significance of immediate post-care practices to support long-term dental health.
